Product Introduction of Disc Dryer
The disc dryer is a highly efficient continuous conduction type drying equipment. The core principle is to conduct heat through the hollow heating disc, causing the material to spread and roll evenly on the disc surface to achieve water evaporation. It has the advantages of high drying efficiency, low energy consumption, and strong adaptability to materials. It can handle various forms of materials such as powder, granules, and paste, and is widely used in the drying and dehydration of materials in many industries. It is particularly suitable for large-scale production scenarios with high requirements for drying temperature and product purity.
1. Scope of application
Application areas | Core Uses |
Fertilizer | Fertilizer raw materials and finished products (such as potassium chloride, potassium dihydrogen phosphate) are dried evenly without damaging the product components |
Inorganic salts | The drying of various inorganic salts (sodium sulfate, magnesium sulfate, etc.) results in good fluidity of the dried material, with a maximum moisture content of less than 0.1% |
Hydrometallurgy | Metallurgical material drying, metal oxide dehydration, tolerance to high concentration feed liquid, high drying efficiency |
Fine chemical intermediates | Intermediate drying and purification, low-temperature drying to retain active ingredients, control material particle size, reduce impurities |
Environmentally friendly | High-salt wastewater crystalline salt drying, sludge dewatering drying, achieving solid waste reduction. |
2. Technical forms and materials
Technical form (disc type) | Core Features | Common materials and compatibility |
Atmospheric disc dryer | Simple structure, easy operation, high drying efficiency, suitable for materials with normal temperature and no special pressure requirements | 304/316L stainless steel (low corrosion), 2205 duplex steel (medium to high corrosion), titanium (strong corrosion), etc |
Vacuum disc dryer | Low-temperature drying, no oxidation, suitable for heat-sensitive and easily oxidized materials, high purity after drying | 304/316L stainless steel (low corrosion), 2205 duplex steel (medium to high corrosion), titanium (strong corrosion), etc |
Iii. Energy Consumption Parameters
Project | Core Parameters (disc dryer) |
Power consumption | 10-20kWh per ton of dry material, mainly for the energy consumption of agitators, fans and auxiliary feeding systems |
Steam consumption | 1.4t steam /1t water, with conduction heating, thermal efficiency up to 70%-85%, energy consumption lower than traditional equipment such as spray dryers and air flow dryers |
Compared with similar products | High thermal efficiency, strong material adaptability, less floor space than drum dryers, suitable for drying various forms of materials |
